Indonesia is indeed prone to hydrometeorological disasters, such as flooding, landslide, and whirlwind, in the rainy season and wildfires or severe drought during the dry season.
Hence, the Indonesian Disaster Mitigation Agency (BNPB) has warned of possible floods, landslides, and whirlwind during the current rainy season.
"Entering the rainy season, the possibility of floods, landslides, and whirlwind increases," Sutopo Purwo Nugroho, the BNPB spokesman, noted in a statement on November 8, 2018.
Precipitation will continue to increase, and the rainy season will peak in January, so the disaster threat is higher.
